Hoarding is a disorder characterized by excessive acquisition and persistent difficulty in discarding possessions. The behaviour has adverse emotional, physical, social, financial, and legal outcomes for the person with the disorder and family members, and might pose a significant public health problem. Hoarding has been included as a distinct disorder in the Diagnostic and Statistical Manual of Mental Disorders Fifth edition (DSM-5). The prevalence of hoarding disorder is approximately 2-6% globally. The current state of the evidence does not offer clear understanding of the causes of hoarding behaviours. A systematic review of the extant literature was carried out to determine the possible causal factors of hoarding behaviours.
This review is conducted in line with PRISMA guidelines. The following electronic databases: Medline through Ovid, EMBASE and PsycINFO were searched for relevant articles published between January 2000 and November 2018. Only articles published in English language were included. Two reviewers independently scrutinized the studies and included them in this review.
Our search strategy returned a total of 396 references. Preliminary findings suggest that individuals with hoarding behaviours may have a genetic susceptibility; abnormal neural activity in the fronto-temporal, para-hippocampal gyrus and insular parts of the brain has also been identified. Traumatic life experiences have also been posited to predispose individuals to hoard.
Although the understanding of hoarding disorder hasgrown in recent years, greater efforts are still needed to clarify the etiology and mechanisms of hoarding disorder as these may help in planning of more holistic interventions to treat the problem.
囤积症是一种以过度获取和持续难以丢弃物品为特征的障碍。这种行为对患者及其家庭成员会产生不良的情绪、身体、社会、经济和法律后果，并且可能构成重大的公共卫生问题。囤积症已被列入《精神障碍诊断与统计手册》第五版（DSM-5）中的一种独立障碍。全球范围内，囤积症的患病率约为 2-6%。目前，囤积行为的病因尚未得到明确的理解。本系统综述旨在对现有文献进行评估，以确定囤积行为的可能因果因素。
本综述遵循 PRISMA 指南进行。检索了以下电子数据库：通过 Ovid 检索的 Medline、EMBASE 和 PsycINFO，以获取 2000 年 1 月至 2018 年 11 月期间发表的相关文章。仅纳入发表在英文期刊上的文章。两名评审员独立筛选研究并将其纳入本综述。
我们的检索策略共返回 396 篇参考文献。初步研究结果表明，囤积行为者可能具有遗传易感性；大脑额颞叶、海马旁回和脑岛等部位的异常神经活动也已被识别。创伤性生活经历也被认为会使个体易囤积。
尽管近年来对囤积症的理解有所增加，但仍需要进一步努力阐明囤积症的病因和发病机制，因为这可能有助于规划更全面的干预措施来治疗该问题。
